Background

SPKI (Simple Public Key Infrastructure) consists of a key certificate and signature formats and associated protocols that support security for a wide range of applications. The SPKI protocol is simple to understand, use, and implement.

The IETF's SPKI working group has produced two RFCs describing theory and requirements. More information is available from Carl Ellison's SPKI Certificate Documentation page. The current SPKI design represents a merger of Ellison's earlier SPKI work and SDSI, developed by Rivest and Lampson at MIT.

Pisces was developed by Jeremy Hylton at CNRI.
